PENCIL-PRINTING MACHINE.

Specification of Letters Patent.

Patented Dec. 9, 1913- Application filed November 9, 1912. vSerial No.780,415.

To all 'wlwm' it may cone-em:

Be it known that I, JESSE B. Soon, a citizen of the United States,residing at Kansas City, in the county of Wyandotte and State of Kansas,have invented certa n new and useful Improvements in Pencil- PrintingMachines, of which the following is a specification.-

This invention relates to pencil printing machines, and has for itsobject to produce a machine by which pencils can be expeditiously andrapidly printed in two colors A further object is to produce a machineof this character in which the pencil is printed by being rolled overtheform, and which, as the printing operation 15 completed, is released.

Another object is to provide means for inking both forms preliminary toeach printing operatiom I With these general objects in view, and othersas hereinafter appear, the invention consists in certain novel andpeculiar features vof construction and organization as hereinafterdescribed and claimed; and in order that it may be fully understoodreference is to be had to the accompanying drawings, in which Figure 1,is a top plan view of a two-color pencil printing machine, embodying myinvention. Fig.2, is a side view of the same. Fig.3, is a centrallongitudinal section of the machine with the ink-distributing rollers intheposition they occupy w forms, and with the pencil roll'ing appliance,automatically raised to inoperative posit-ion to avoid interfering withthe inking of the forms. Fig. 4, is a top plan view of the machine withthe pencil rolling mechanism swung to an upright position, the form andplate being omitted to disclose the underlying mechanism. Fig. 5, is adetail perspective view of one of the inking-disk-carrving bars. Fig. 6,is a detail perspective view of a cam-carrying rock-lever forming partof the machine.

In the said drawings. 1 indicates the base of the machine, 2 the sidewalls formed to provide a pair of upwardly projecting standards 4.

5 is a series of bolts connecting the semihexagonal standards,

en inking the.

and secured to said bolts are bars 6, the outer faces of whichpreferably parallel the upwardly-converging edges of the standards 4.

7 is a disk arranged with its outer face para leling the adjacentinclined edges of the semi-hexagonal standards, and provided with aspindle 8, journaled in the adiacent bar 6, and retained in position awasher 8, and a key 9, and said disk is provided at its inner side witha series of radial teeth 10. A similar disk 11, is arranged with itsouter face parallel with the other inclined edge of the semi-hexa onalstandards and is provided with a spind e 12 journaled in the adjacentbar 6, and is retained in position by a washer 13, and a key 14, andsaid disk 11, is provided at its inner side with radial teeth 15.

16 is a crossbar connecting the semi-hexagonal standards centrallybetween the disks 10 and 11, and 17 is a horizontal rock lever carriedby and underlying lever 16, and equipped at its rear end with a pivoteddog 18, adapted under the action of spring 19 to lie in the path ofteeth 10, of disk 7, and to be capable of yielding so as to slip oversaid teeth when the lever rocks in one direction. A similar dog 20 ismounted on the other end of the rock lever 17, and is held by a spring21 in position to engage the teeth 15 of disk 11'.

22 is a cam plate depending from rock lever 17, and provided with aflange 13 at its upper end, underlying and secured to said rock lever byrivets 24.

25 is a rocker shaft journaled in the semihexagonal standards of theframe, and pro- "ided with an arm 26. which in each rocking action ofsaid shaft, engages the cam 22 and thus operates the rock lever. Thefirst operation, which occurs as the rock arm swings forward or to theright, imparts rotatable movement to disk 7 and seats dog 20 inengagement with a tooth of disk 11. On the back movement said armstrikes the rear portion of the cam and rocks the lever back to itsinitial position. and in so doing returns dog 18 to its initial positionand imparts rotation to diskll through the instrumentality of dog 20.

To impart movement. to rock shaft 25, it is provided with a gear wheel27 meshing with gear wheel 28 mounted on rock shaft 29 which is equippedat one end-with an operating handle 30.

Secured to the outer side of each semihexagonal standard by screw bolts31 isa pair of semi-hexagonal shaped tracks 32 and 33, the tracks 32being interposed between said standards and tracks 33. The tracks 32 and33 are of identical construction but are arranged in reversed positions,so that the left hand edges of tracks 33 project rearwardly beyond thecorresponding edges of tracks 32, and the right hand edges of tracks 32project forwardly beyond the corresponding edges of tracks 33, it beingalso noted that the right hand ends of the upper portions .of tracks 32and the left hand ends of the abutting upper portions of tracks 33,respectively, project above the upper edges of the remaining portions ofsaid tracks as at 34 and 35 respectively, and that the adjacent ends ofsaid portions 34 and 35 are inclined, as shown clearly in Fig. 2.

At opposite sides ofthe frame, the shaft.

25 carries a pair of I-shaped frames 36, the stem portions of saidframes extending through said shaft and being secured rigidly thereto bynuts 37, whereby said I- frames are clamped tightly against the shaft. v

38 is a pair of rods slidingly mounted in the frames 36 and terminatingat corresponding ends in hooks 39, forming journals for the ends of thespindle of an inking roller 40, and said roller is vprovided with trackrollers 41 to travel upon the tracks 32, and to hold said rollers inengagement with said tracks, springs 42 are -m'ounted upon rods 38 andexert pressure at their opposite ends against the frames 36 and collars42 mounted on rods 38.

43 are rods extending slidingly through frames 36 and terminating atcorresponding ends in hooks 44 formingjournals for the spindle of theinking roller 45, and said roller is provided with track rollers 46engaging tracks 33 and held in engagement with said tracks by springs 47mounted on (rods 43, and bearin against frame 36 and collars 48 of saidr0 s 43.

49 are spacer strips mounted upon the standards 4, and bridging thespace therebetween, and securedupon the strips 49, is a bed plate 50,upon which is mounted a chase 51, in which is secured as shown or in anyother suit-able manner, a pair of forms 52 and 53 the same extending inparallel relation and transversely of the machine.

From the foregoin it" will be apparent that by rocking hand? 30 to theleft, shaft 25 is turned in the direction indicated by the arrow Fig. 3,and as hereinbefore explained, turns disk 7 one step. Said movement ofshaft 25 is participated in by frames 36, so that the inkingrollerstravel upwardly, then horizontally and then downwardly,substantially parallel with the edges of the semi-hexagonal standards 4.In the upward movement, the roller 40 operates in engagementwith theface of the disk 7, and receives ink therefrom, the roller 45 travelingin the same direction but above and out of contact with said disk. Asthe rollers travel over the top of the standards; 4, the rollers 41first travel upon the depressed portions of tracks 32 so that the roller40 shall engage and ink the form 52, and as it clears said form, saidtrack rollers 41 ride upwardly on the elevated portions 34 of saidtracks, so that during the remainder of the travel in the directionindicated, that is forward, roller 40 shall pass over form 53 withouttouching the same, it being also noted that as rollers 41 traveldownwardly on the tracks32, the roller 40 cannot contact with disk 11.In the same operation,, the rollers 46, travel over the elevated portion35 of tracks 33, and then descend onto the'depressed portions of saidtracks, and the roller 45 being in advance of roller 40, is carried overform 52 without contact therewith and then drops down into engagementwith form 53, and during the remainder of its forward travel, comes intocontact with and receives ink from disk 11. As the handle 30 is thrownback to its initial position, the rollers are returned to their originalpositions and at the same time the rock lever, as hereinbeforeexplained, imparts rotation to disk 11, the track rollers and inkingrollers reengaging in their return movement, the same parts which theyengaged in their forward movement, it being understood that the trackrollers drop down from the high portions of the tracks to the lowportions through the retractile action of their respective springs, and,said springs yield to permit the track rollers to climb the highportions of the tracks.

'56 is a cross bar connecting standards 3,

and hinged thereto at 57 is a plate 58, provided with a pair of forwardarms 59, which, when the plate is horizontal, overlie the chase attheopposite sides thereof, the said arms having depending strips 60 torestupon the form when the printing operation is in progress, and one ofthe arms 59 is provided with an extension 61 terminating in an upwardlyprojecting stop 62 for a purpose which hereinafter appears, and both ofsaid arms-are rovided' at their upper sides with thin friction tracks63, whereb the possibility of slippage of a pencil being printed, isguarded against.

64 is a pair of arallel walls rising from plate 58, and 65 1s a platesecured thereto tall Leanna and terminating forward of plate 58 in anarm 66, which constitutes an abutment or gage against which each pencilto be printed, is thrust, in order that the printing of the pencilsshall be in at the same distance from the butt end t ereof.

67 is a bar secured to plate 58, and about midway the length of saidplate, said bar is bent outwardly and then extends forwardly at 68 andat its free end is bent upwardly slightly at 69 so as to lie above a pin70 projectin inwardly from handle 30, so that when t e handle is swingto the left, the pin shall engage bar 68 and swing the plate 58 upwardlyto give the inking rollers free passage over the disks and the forms. Asthe rollers descend over disk 11 plate 58 drops downward to its originalposition. As t e movement of the handle 15 reversed, the pin 70 againengages rod 68 and swings plate 58 u wardly to permit the inking rollersto pass ack to their orig inal positions. As the rollers start downward,the plate 58 drops back to its original position.

71 are retainer clips secured to and projecting inwardly from walls 64over a slide plate 72 fitting between walls 64 of plate 58. 73 aresprings interposed between said plates, and disposed so as to hold thefront end of plate 72 elevated above plate 58 a distance in excess ofthe diameter of a lead pencil, and said plate 72 is provided at itsunder side in the vertical lane of friction track 63,with frictiontracks4. Nearitsrear end and centrally between its side margins, plate 7 2 isprovided with a spacing head 75 ada ted to slide back and forth uponplate 58 uring and after each printing operation, as hereinafterexplained, and projecting upwardly from the rear end of plate 58 13 anarm 76, the same bein secured to plate 58 by a clamping screw 7?.

78 is a retractile sprin secured at its rear end to standard 76 an atits front end to a standard 79 rojecting upwardly from plate 72 near thefi-ont end of the latter, and said spring tends to hold plate 72 thrownback against standard 76, as shown in Fig.3.

80 is a standard mounted upon late 72 near its rear end, and saidstander in conjunction with standard 79, forms 0. sup port for a tubularhandle 81, which incloses spring 78 for the greater part of its length.

To accommodate the device for operation with en holders, screws 82extend up throug the right hand track 74 and through transverse slots 83in slide plate 72, the slots accommodatin lateral adjustment of saidtrackway, an nuts 84 enga said screws 82 to ri 'dly secure said tracE atthe desired point 0 adjustment along the length of said slots. It isobvious that where one extremity of an ob ect, such as a enholder, istapered, one o the tracks 7 must be shifted so as to engage a part ofthe object where it is of the same diameter as where engaged by theother track 74, otherwise the object or penholder would not maintain itsposition at right angles to its direction of travel upon the frictiontracks 68.

Assuming that the parts are in position shown in Fig. 1, and that thelead pencil to be printed is laced upon the tracks 63 and against theront end of walls 64 and with one end against the gage 66, it will beapparent that by reference to Fig. 3, that the front end; of tracks 74will overlie the pencil, as shown in full lines Fig. 2, and dottedlines, Fig. 1.

Assuming that the form has just been inked, the operator grasps handle81, and applying pressure thereon to cause tracks 74 to engage thepencil, slides said plate forwardly and thus causes the pencil to rollin the same direction, the forward movement of the plate being limitedby contact with the sto 62, at the same moment that the pencil a rmaking two complete revolutions, reaches the front extremity of the arms59, from which it rolls or is caught by a conveyor (not shown) or byhand. At

the same time the handle of the slide plate is released to permit the 5ring 78 to return the former to its initial position, the spring 7 3again raising its front end so that a second pencil may be placed inoperative position. Immediately after the slide plate returns to itsoriginal position, the operator rocks handle 30 to the left and backagain, for the purpose of reinking the forms, it being understood thatthe disks may be inked by hand or in any other suitable manner, and thatthe inks will be of different shades or colors, one of the colors beingprinted on the pencil on thefirst revolution of the latter and the othercolor in the second revolution.
